FT will not ship to places, other than these 2 zones via air mail.
Developments: 14 Apr 2015:
FT is able to ship via Sweden Post to my country, with estimate delivery date of 13-25 days now! You may want to check if Li-ION shipping is allowed to your country.
6 Aug 2014:
FT sending via Hong Kong Surface Mail.
I bought 2 for around $18 from FT. I used to buy them from a seller on ebay who would sell them for 20.65/pair (got them in 2-3 days also) but he raised them to 22-23/pair.
I have bought LOTS of flashlight-related stuff from FT that the discount code didn't do squat for. For me, it works on so few items I don't even bother using it anymore.
Cautionary: much isn’t yet understood about lithium-ion (and the people making them aren’t disclosing how they’re made or tested)

—— quote——
… fire event showed evidence not just of an internal thermal runaway but that “unintended electrical interactions occurred among the cells, the battery case, and the electrical interfaces ….” …. there is no standardized thermal runaway test that’s conducted in the environment and conditions that would most accurately reflect how the battery would perform when installed and operated …. might not have adequately accounted for the hazards associated with internal short circuiting.

… deciding what the safety standards should be has become the pursuit of an ever-moving target.
The more that lithium-ion battery technology develops, the more it appears
that the battery industry doesn’t fully understand the ways in which the technology can fail.
A commonly-used euphemism for this phenomenon is that the technology “is not yet mature.”
…
… a two-day public hearing to track the history of lithium-ion battery development … was openly frustrated by the lack of information …. related to the composition of the membership …. developers and manufacturers of lithium-ion batteries who are … lawyered up and ready to invoke proprietary secrecy and intellectual property rights to protect themselves from competitors. This materially affects what can be revealed about the behavior of batteries during testing….

Testing? What testing?
Just sell them to the electric-cigarette manufacturers.
Their customers will test them.
After all, what’s the worst that could happen?
They can’t be more dangerous than nicotine ….

There are two different places you can enter a coupon code on FT. One when viewing the cart and one on check out irrc. Only one of the places actually works with the BLF coupon, but I forget which one.
